内に送風されている。2. Description of the Related Art Conventional air conditioning in relatively old hotel guest rooms is
It is usually operated by two air conditioning systems. The first air conditioning system is an air conditioning system that sends hot or cold water generated in the machine room to the fan coil unit installed in each guest room, and blows warm or cold air that has undergone heat exchange with the coil into the room with a fan. In the second air conditioning system, hot air or cold air generated by an air conditioner installed in the machine room that can introduce outside air is sent to the cabin by a duct and then blown into the room. Normally, only one air outlet is formed in the guest room, and warm air (cold air) from both the first and second air conditioning systems is blown into the room from this single air outlet.

客の要望に応ずることが出来るようになっている。This first air conditioning system has a structure for switching between the cooling period in summer or the heating period in winter to flow cold water or hot water through a pipe for cooling or heating, and hot water or cold water is used as an outflow pipe. It is sent in a two-pipe system with a return pipe. Therefore, it is impossible to switch between cooling and heating at any time. On the other hand, the second air conditioning system is a structure that blows cold air or hot air generated by an outside air introduction type air conditioner installed in the machine room to the cabin through a duct, and generates cold air or hot air at any time. Since it is a system that can be sent by sending, it functions as a complementary system of the first air conditioning system, and during the cooling period or the heating period of the first air conditioning system, it sends cold air or warm air to assist the first air conditioning system,
It functions as an alternative system when the first air conditioning system fails. Furthermore, in the middle period when the first air conditioning system does not enter the cooling period or the heating period, heating or cooling individual rooms by sending warm air or cold air according to the request of the guest, and responding to the request of the guest You can do it.

The heating period is said to be from November to February, but in hotels where there are many Japanese middle-aged and elderly people, the first air conditioning system is operating in the heating mode from around October in the fall to around May in the spring. . Therefore, if the guest complains that the room temperature is high at such times, the second air conditioning system will send more cool air to the guest room through the duct, but the fan coil unit in the guest room will have hot water. Therefore, about half of the cold air blown out from the duct is blown out from the air outlet while being warmed by the hot water of the fan coil unit, and there is a problem that the room temperature cannot be lowered sufficiently. there were. Such a problem makes it difficult to meet the demand of approximately 30% of foreign guests per year, which tends to be hot, and there is a risk of losing a considerable number of guests.
The air from the duct is blown directly into the passenger compartment without being affected by the fan coil, and the fan coil unit
It works to stir the air in this cabin.

However, it is very costly and time consuming to renovate a 2-tube hotel air-conditioning system into a 4-tube system, which is practically impossible at a hotel currently in operation.

る。SUMMARY OF THE INVENTION In a hotel with a two-pipe type air conditioning system, the present invention provides hot water from the first air conditioning system in each guest room regardless of the operation mode of the first air conditioning system. (Cold water) is blocked from flowing to the fan unit coil, and cold air (warm air) from the second air conditioning system is introduced into the room without being warmed (cooled) by the fan coil unit, making it possible to individually control the room temperature. The purpose of the present invention is to provide a hotel air-conditioning method that can bring an air-conditioning effect comparable to that of the 4-pipe system with low cost and short construction period.
